Hiller is at least worth a roster player and a second round pick if not a first. He's a proven starter and proven starters do not grow on trees. Buffalo will find this out pretty soon if they trade Miller.

Guastad got a 1st, and he's a 4th line center that happens to be good at faceoffs. Hiller should be able to get a late first and one of 3rd line player/prospect/5th dman. I would try for a young promising prospect though, like Ryan Strome.

Ducks get
Ryan Strome

Islanders get
Hiller

Good hockey trade for both teams, Hiller has one year left and tries to prove himself that he is still capable and Islanders get the number one goalie they need if they choose not to go with Nabakov after those playoff games he just had. Ryan Strome will fill the void for the future second line center and battle it out with Holland while Bonino is in the better fit role as 3rd line center.

Edit: Right now in we have Hiller/Fasth/Anderson/Gibson. Anderson had a phenomenal year in the AHL and played in the same league as Fasth before coming to N.A. and was almost on par with him. Its risky to trade Hiller but now would be the time.
